OIL BURNER.

Application nled October 10, 1928. Serial No. 667,654..

To all rwhom z'tmay camera.'

Be it known that I, GEORGE M. BUCEY, a citizen of the United States,residing at Kansas City, in the county of Jackson and 6 State ofMissouri, have invented certain new and useful Improvements in OilBurners; and I do declare the following to be a full, clear, andexactdescription of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and-to the figures of reference markedthereon, which form a part of this specification.

This invention relates to hydrocarbon burners and it is particularlyadapted for burning oil and in order to facilitate combustion, I haveprovided means for introducing water vapor in the combustible mixture.Ihave also provided means whereby gas may be used in connection with apilot burner t'ignite the oil and water vapor mixture which of course iscombined with an appropriate amount of air. The invention consists ofcertain novel parts and combination of parts all of which will bespecifically referred to hereinafter, reference being had to theaccompanying drawings in which:

`Fig. 1 is a perspective view of a burner constructed in accordance withmy invention.

Fig. 2 is a vertical, longitudinal, sectional view through the burner.

Fig. 3 is 'a fragmentary sectional view through part of the burnershowing the reciculating port, and p Fig. 4 is a disassociatedperspective view ofthe vapor nozzle and means for connecting it to theburner shroud.

Referring now, to the drawings by numerals of reference, i

1 designates a base pan having a truncated conical bottom 2 in thetruncated poi'- tion of which is a cylindrical distributor 3 having a to4 provided with an oil outlet orifice 5 an a gas tip 6, the gas tip issupplied with gas by a pipe 7 so that the gas tip constitutes a pilotburner and the orifice 5 receives an oil pipe 8 which supplies oil tothe 5 burner. The distributor 3 is provided with a plurality ofcircumferential trough shaped flanges 9 10 and 11 thelatter of which is.

part of the truncated portion of the conical bottom 2 and the anges forprogressively increasing diameters Afrom the top to the bottom and areprovided for the purpose of distributing oil overiiowing through theoriice 5 about the burner. The bottom 2 is provided with a truncatedconical distributor casing 12 spaced from the distributor 3 and providedwith outlet openings 13 and 14, the former being about midway of thecasing and the latter at the base of the casing so that vaporized oilmay pass through the opening 13 or 14 to be mixed with air and steampreparatory to being ignited. The top of the casing 12 is also spacedslightly from the distributor 3.and it carries an inverted cup basedelector 15 so that the oil burners will be directed downwardly. Thecasing is surrounded by a cylindrical shroud 16 having inlet openings 17connected to air inlet openings 18 in the base bv the angular pipes 19which constitute air ports for supplying air to mix with the vaporizedoil, the angular pipes 19 being disposed radially about the axis of theburner to supply air towardthe center. The shroud is provided with avertical elongated circulating pipe or port 20 so that some of the aircan be distributed at the top of the shroud and mix with water vapor.The water vapor is admitted through an elongated vertical pipe 21 havinga right angular extension or elbow 22 discharging into a hollow head orchamber 23 provided wit-h a discharge nozzle 24 which discharges in thespace between the deflector cap 15 and the top of the shroud 16. Thewater vapor is provided by admitting water into the pipe 21 through asupply pipe 26 there being an overflow pipe 27 in the bottom of the pipe21 so thatthe level of the water in the pipe 21 may be controlled. At

the top of the pipe 21 is a hinged relief valve 28 whlch will unseatwhen the vapor appreciably exceeds atmospheric pressure so that. thevapor can escape to atmosphere. The head 23 is providedwithdiametrically oppositely located lugs 2Q and 30 which are adapted tobe received in the spaces 31 between the segmental anges 32 and 33 inthe locking ring 34 which is also provided with spaced segmental flanges35. and 36. When the head is to be secured to the shroud the lugs 29 and30 are dro ped in the spaces 31, at which time the hoo shaped lockinglugs 37 and 38 on the top of the shroud are 1n line with the spaces 39and 40 between the flanges 35 and 36 of the ring. Then the ring isturned slightly so that the lugs 29 and 30 will ride under the flanges32 and 33, the flanges preferably being in the form of cams and when thering is turned to cause the lugs 29 and 30 to ride under the flanges 32and 33, the flanges 35 and 36 ride under the hook shaped lugs 37 and 38,thereby locking the head in place. As previously explained the pilot jetor burner 7 is always supplying a pilot flame for the burners. If thevalve (not shown) controlling the supply of oil through pipe 8 isopened, oil will be admitted through the orifice 5 and flow over thedistributor on to the flange 9. If a small amount of oil is permitted toflow through pipe 8 the oil will be ignited before it can overflow on toflange 10 or on to flange 11. Air will be supplied through the pipe 17and when the pipe 21 becomes hot enough some of the vapor formed by thewater provided by the pipe 21 will be generated into vapor, dischargedthrough 24 to mix with theH air and oil vapor so that such mixture maybe ignited but if the flow of oil through pipe 8 is increased some of itwill flow over into the trough shaped flange 10, the vapor beingdischarged through orifice 13 and when a 'maximum amount of oil is fedthrough pipe 8, the oil will flow over into the trough shaped flange 11so vapors will issue from the space surrounding the distributor throughthe space between the distributor casing .and the distributor proper andthrough the openings 13 and 14 it is then the maximum flame will beprovided and it will be apparent that. the greater the flame the morerapid the oil will be generated into va or so that the amount of vaporcombined with the hydrocarbon will be in proportion to the demand.

The device may be easilyconstructed. It will be of rugged constructionso that it will not readily warp or distort and it may be easilyassembled or disassembled for inspection or repairs. The port 20 willallow part of the air to circulate throu h this port and through thespace surrounded by the shroud which will tend to thoroughly co-minglethe various constituents of the mixture.

The pi e 7 is provided with a valve 7 so that the ow of gas for the tip6 may be controlled, it being understood while I have referred to thet1p 6 as a pilot tip or burner, the gas will be supplied through the tip6 only during the time it is necessary to start the oil fuel burning,then the valve 7 can be seated because it will not be necessary to burnthe gas while the oil is burning. The yoil supply can be controlled by avalve 8.
